Hi there people not a happy bunny at the mo, been under my gt3 fitting a exhaust and I found wot seems to be a rust crack along the seal it's about 10 inches long and goes towards the middle about 6ish inches . It's basically an L shape.
Does anyone know if it's a big job to repair any info much appreciated.
